我想做一个下拉菜单，当我单击一个项目时，下拉菜单会发生变化，但我不知道如何做到这一点，而且我对此一无所知。那是我的代码： 

<div>
    <div class="relative">
      <!-- Dropdown toggle button -->
      <button
        @click="show = !show"
        class="flex items-center text-gray-500 rounded-md"
      >
        <span class="">Language</span>
      </button>

      <!-- Dropdown menu -->
      <div
        v-show="show"
        class="
          absolute  right-0   py-2  mt-5
          rounded-md shadow-xl w-36 bg-white
          
        "
      >
        <router-link
          to="/"
          class="
            inline-flex
            w-full px-4 py-2
            text-sm text-gray-500
            hover:bg-indigo-200 hover:text-indigo-600 
          "
        >
        <img src="../Assets/Img/en.png" alt="" class="w-6 h-4 mr-2">
          English
        </router-link>
        <router-link
          to="/"
          class="
            inline-flex w-full px-4 py-2
            text-sm text-gray-500
            hover:bg-indigo-200 hover:text-indigo-600
          "
        >
        <img src="../Assets/Img/fr.png" alt="" class="w-6 h-4 mr-2">
          French
        </router-link>
        <router-link
          to="/"
          class="
            inline-flex w-full px-4 py-2 text-sm text-gray-500
            hover:bg-indigo-200 hover:text-indigo-600
          "
        >
        <img src="../Assets/Img/de.png" alt="" class="w-6 h-4 mr-2">
          German
        </router-link>
        <router-link
          to="/"
          class="
            inline-flex w-full px-4 py-2 text-sm text-gray-500
            hover:bg-indigo-200 hover:text-indigo-600
          "
        >
        <img src="../Assets/Img/pt.png" alt="" class="w-6 h-4 mr-2">
          Portuguese
        </router-link>
      </div>
    </div>

这就是我所做的：

selectedLang不要在@click 中使用selected lang，也不要使用@click.native，只有点击才有效

添加另一个名为的属性selectedLang并在单击其中一种语言时对其进行更新：

data(){
 return{
    show:false,
    selectedLang:null
   }
}

为模板添加@click.native="selectedLang='theCurrentLanguage'"每个语言项：

   <!-- Dropdown toggle button -->
      <button
        @click="show = !show"
        class="flex items-center text-gray-500 rounded-md"
      >
        
        <span class="" >{{selectedLang??'Language'}}</span>
      </button>

      <!-- Dropdown menu -->
      <div
        v-show="show"
        class="
          absolute  right-0   py-2  mt-5
          rounded-md shadow-xl w-36 bg-white
          
        "
      >
        <router-link
          to="/"
         @click.native="selectedlang='English'"
          class="
            inline-flex
            w-full px-4 py-2
            text-sm text-gray-500
            hover:bg-indigo-200 hover:text-indigo-600 
          "
        >
        <img src="../Assets/Img/en.png" alt="" class="w-6 h-4 mr-2">
          English
        </router-link>
